The Shaggy's Power meme, often referred to as Ultra Instinct Shaggy, reimagines the cowardly Shaggy Rogers from Scooby-Doo as a god-like entity with limitless strength. The trend originated around 2017 when a fan-made video combined Shaggy's fighting scenes from 'Scooby-Doo! Legend of the Phantosaur' with the 'Ultra Instinct' theme from Dragon Ball Super. It quickly evolved into a popular 'Chuck Norris' style legend where Shaggy is depicted as an unstoppable force who only needs to use a tiny fraction of his power to defeat any fictional character. This meme is a staple of internet culture for subverting expectations of weak characters into omnipotent beings.
